Definitions

  • This invention relates to an electric device with an operation indicating lamp which may be used with a solid state relay and, more particularly to an improved device which can be easily assembled.
  • An electric device which is used for a solid state relay and has a light emitting diode (LED) as an operation indicating lamp is well known.
  • the LED is electrically connected to a circuit board and can be seen through an indicating hole disposed in the front cover of a case.
  • a packing is interposed between the base of the LED and the front cover.
  • the case is filled with a resin material which is injected through an opening in the case. The resin in set to fix the position of the circuit board and the electric components mounted on the board.
  • an electric device with an operation indicating lamp comprising a base; a case transversely divisible into a main frame and a case cover, the main frame being fitted to the base and the case cover having an indicating hole; an operation indicating lamp visible through the indicating hole provided in the case cover; and a resin material for fixing the components in the case, the resin material being injected into the space provided by the base and the main frame.
  • the device includes a case 2 which is divisible into a main frame 3 and a case cover 4.
  • the case 2 is fitted to a base 1 at an open end of the main frame 3.
  • a circuit board 5 is electrically connected to a plurality of terminals 6 which protrude from the base 1.
  • An LED 7 serving as an operation indicating lamp is electrically connected to the circuit board 5 and visible through an indicating hole 2a of the case cover 4.
  • a resin material 8 is injected into the space provided by the base 1 and the main frame 3 and set to fix the circuit board 5 and the components mounted on the board 5.
  • the LED 7 is positioned on the board 5 so that the top thereof slightly protrudes from an edge of the board 5 and is electrically connected to the board 5. Then, the board 5 is vertically set and electrically connected to the terminals 6. Subsequently, the main frame 3 is fitted to the base 1 at one open end of the frame 3. The resin material 8 is injected into the space provided by the base 1 and the main frame 3. Finally, the case cover 4 is fitted to the other open end of the main frame 3 so that the LED 7 can be seen through the indicating hole of the case cover 4.
  • the resin material 8 does not leak from the indicating hole 2a and the gap between the LED 7 and the indicating hole 2a.
  • the LED 7 does not need to be continuously pushed against the case cover 4, preventing cracks from developing in the solder connecting the LED 7 to the circuit board 5 and allowing the easy assembly of the device. Further, because no packings are required for preventing the resin leakage, the LED 7 can be positioned precisely.
  • Figs. 3 through 6 showing an electric device in accordance with a second embodiment of this invention
  • guide grooves 4c, 4c on case cover 4 are respectively engaged with guide rails 3c, 3c which are longitudinally provided along the longer edge of the open end of the main frame 3.
  • the case cover 4 is slid along the guide rails 3c, 3c to plug the open end of the main frame 3.
  • the case cover 4 has a protrusion 4b with which the cover 4 is locked to the open end of the main frame 3 (See Fig. 5).
  • the indicating hole 2a is tapered with the inner diameter smaller than the outer one. Because the minimum diameter of the hole 2a is smaller than the diameter of the LED 7, a gap is not developed between the hole 2a and the LED 7 even if the LED is positioned with a deviation from the normal position, preventing foreign matter such as dust from entering.
  • the guides 4d, 4d of the case cover 4 are respectively engaged with the guide grooves 3d, 3d provided at the open end of the main frame 3.
  • the case cover 4 is slid along the guide grooves 3d, 3d to plug the opening end of the main frame 3.
  • the case cover 4 has four locking holes 4e, and the main frame 3 has four locking pieces 3e at the open end.
  • the cover 4 is mounted to plug the open end of the main frame 3 by locking the pieces 3e to the holes 4e.
  • the indicating hole 2a provided on the cover 4 is tapered with the outer diameter smaller than the inner one. Because the minimum diameter is smaller than the diameter of the LED 7, the LED 7 is positioned by the inner wall of the hole 2a leaving no gap between the LED 7 and the hole 2a.
  • a bar 4g disposed on the cover 4 is fixed by the resin, preventing the cover 4 from coming off the main frame 3.
  • the cover 4 has four locking pieces 4f, and the main frame 3 has four locking holes 3f at the opening.
  • the cover 4 is mounted to plug the open end of the main frame 3 by locking the pieces 4f to the holes 3f.
